The Data Exploration & Analysis Portal (DEAP)

The Data Exploration & Analysis Portal (DEAP) is a web-based platform designed to help researchers efficiently access, explore, and analyze data from the Adolescent Brain Cognitive Development (ABCD) Study and the Healthy Brain and Child Development (HBCD) Study through the NIH Brain Development Cohorts Data Hub.

DEAP provides intuitive tools for exploring dataset metadata, including a tree-based filter that organizes variables by research domain and a data dictionary explorer that allows users to explore variable-level metadata and descriptive statistics. Researchers can create and download custom datasets in multiple file formats. Additionally, researchers can use the extensive built-in capabilities for visualizing and exploring data as well as perform complex analyses (including neuroimaging analyses) using the fast and efficient mixed effects algorithm (FEMA) and visualize their results.

Datasets, visualizations, and analyses can all be stored, locked, and shared with other users, enabling collaborative and reproducible science.

Key Features

• Tree-based filter & data dictionary explorer
• Individual-level variable details covering variable metadata, descriptive statistics, and hyperlinks to study documentation
• Custom dataset creation & download in seven file formats for use in various statistical software packages
• Customizable charts, graphs, and tables to explore the data (10+ visualization formats)
• Analysis, including neuroimaging data, using fast and efficient linear mixed effect modeling (FEMA)
• Organization of objects using labels & projects (datasets, explorations, and analyses)
• Sharing, locking, and archive objects (datasets, explorations, and analyses)

The Data Exploration & Analysis Portal can be used for exploring study data dictionaries and viewing variable details (including individual variable-level aggregate statistics) without a NBDC data use certification. Additional features require study data access.

Collaborators

DEAP is a collaborative project between the ABCD Data Analysis, Informatics & Resource Center at the J. Craig Venter Institute, ZevRoss Spatial Analysis, and Blue Rock Software. The web-based neuroimaging visualization tool is built on the tool NiiVue.
